[basex-talk] Java type mismatch when reflecting.

Hi

I can successfully create an object instance of https://www.stringtemplate.org/api/index.html when using the parameter-less default init:

declare namespace ST = 'java:org.stringtemplate.v4.ST';     let $template := "Hello <who>"     let $stInstance := ST:new($template)     let $call := ST:add($stInstance, "who", "World!")     return ST:render($stInstance)

Template delimiters can be changed by supplying left and right delimiters (type char) upon init (by default ST4 uses < and > as template delimiters). The signature for this would be:

ST(java.lang.String template, char delimiterStartChar, char delimiterStopChar)

Documentation is at https://www.stringtemplate.org/api/org/stringtemplate/v4/ST.html#ST-java.lan...

So I defined the types at invocation, but executing following code I get an error.

declare namespace ST = 'java:org.stringtemplate.v4.ST';     let $template := "Hello $who$"     let $stInstance := ST:new·java.lang.String·char·char($template,"$","$")     let $call := ST:add($stInstance, "who", "World!")     return ST:render($stInstance)

The error is:

[XPTY0004] java.lang.IllegalArgumentException: argument type mismatch.     Caused by: org.stringtemplate.v4.ST(String, String, String).

The query plan of this unsuccessfull invocation is:

<QueryPlan compiled="true" updating="false">       <GFLWOR type="item()*">         <Let type="item()*" name="$stInstance" id="1">           <DynJavaConstr name="org.stringtemplate.v4.ST" type="item()*">             <Str type="xs:string" size="1">Hello $who$</Str>             <Str type="xs:string" size="1">$</Str>             <Str type="xs:string" size="1">$</Str>           </DynJavaConstr>         </Let>         <List type="item()*">           <ProfVoid name="prof:void" type="empty-sequence()" size="0">             <DynJavaFunc name="org.stringtemplate.v4.ST:add" type="item()*">               <VarRef type="item()*" name="$stInstance" id="1"/>               <Str type="xs:string" size="1">who</Str>               <Str type="xs:string" size="1">World!</Str>             </DynJavaFunc>           </ProfVoid>           <DynJavaFunc name="org.stringtemplate.v4.ST:render" type="item()*">             <VarRef type="item()*" name="$stInstance" id="1"/>           </DynJavaFunc>         </List>       </GFLWOR>     </QueryPlan>

I can see no deviation from https://docs.basex.org/wiki/Java_Bindings#Functions_and_Variables in my code. What am I doing wrong? Thanks.
